To create a simple RF Gain test, we need to add buttons to the test panel. We will simply copy and paste a GAIN measurement button from the Tester Viewer window to the test panel.
Open the Tester Viewer window
Selet View from the Tester menu from the Test Plan Editor.
If the Tester Viewer window is already open on the computer screen, just select the title bar on the Tester Viewer window or any other location on the window to make it the active window.
The system will display the Tester Viewer window.
"Select" to Copy the Desired Button
Scroll down the instrument list and select the vna instrument.
Select the amplifier meas button.
Copy the MEAS GAIN button by placing the mouse pointer on the MEAS GAIN button, click mouse button 2 and click Select on the pop-up menu.
The Tester Viewer Window will indicate that you have selected and copied the GAIN measurement button by highlighting the button.
Paste the Button into the Test Panel
Change the active window back to the Test Plan Editor window. (Select the title bar on the Test Plan Editor window or any other location on the window to make it the active window.)
Paste the button on to the test panel by placing the mouse pointer at the location desired on the test panel, click mouse button 2 and select Paste Button from the pop-up menu.
Organizing the Test Panel
To change the position of the button in the test panel, place the mouse pointer on the button, press and hold mouse button 2, and drag the test button to the location desired. Release the mouse button when finished.
Copying, Pasting, and Moving Buttons
The process for copying, pasting, and moving other buttons from the Tester Viewer Window is the same. Go to the Tester Viewer Window, select the instrument, select the button type, copy the button, return to the Test Plan Editor, paste the button in the test panel desired, and move the button where you want it.
Changing From Single Value to Ranged Button
Changing from Single Value to Range
A button's behavior can be changed from a single value to a range with user defined start, stop, and step values.
The Source1 FREQUENCY button will change to a Source FREQUENCY START/STOP/POINTS button.
Each of the settings buttons shown is actually a collection of objects or buttons which have been grouped together. For example the DutControl Vcc 1 settings button shown consists of five buttons: a START voltage button, a STOP voltage button, a POINTS button, a Vcc 1 settings button, and a DutControl button. The START, STOP, and POINTS buttons have been grouped together inside the Vcc 1 settings button, which in turn is inside the DutControl instrument (owner button). Combined together they create a START/STOP/POINTS Vcc 1 DutControl settings button. The DutControl and Vcc 1 buttons are called group buttons. The DutControl button is an instrument owner button and the Vcc 1 button is a settings group button.
Modifying Button Settings
To modify the values for a settings button, click mouse button 1 on the desired setting you want to change.
For example, to change the start frequency value for Source1:
Place the mouse pointer on the START button inside the Source1 FREQUENCY settings button and click mouse button 1.
The system will display a "Enter a Number" dialog box.
Enter the new value desired. ("1500" was entered in the example shown)
Press the ENTER key or select the OK button.
The new value is now displayed in the START FREQUENCY settings button.
The RI System Software offers many different buttons for each of the physical and virtual instruments in the system. In the example shown, we have a source frequency button, a source power level button and a DC supply voltage button for VCC1. The system offers many different singe test point buttons such as the Source POWER settings button shown. You can then create multiple test point button such as the Source FREQUENCY settings button and the DutControl VCC1 supply voltage settings button by using the Range function. (We will be discussing the Range function in a later lab.)
As you can see, several buttons can be added to the same test panel. The system performs the GAIN measurement for each combination of the test points specified by the settings buttons. In the example shown, the vna will perform the GAIN measurement for 24 different conditions (6 frequency x 4 voltage levels x 1 power level).
